Claims.

The present invention relates to a device for separating coins ofvarious denominations from each other, and depends for its operationupon the'varying diameters of coins of different denominations.

Objects and advantages of the invention will beset forth in parthereinafter and in part will be obvious herefrom, or may be learned bypractice with the invention, the same being realized and attained bymeans of the instrumentalities and combinations pointed out in theappended claims.

The invention consists in the novel parts, constructions, arrangements,combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and constituting a parthereof, illustrate an embodiment of the invention, and together with thedescription, serve to explain the principles of the invention.

Of the drawings:

Fig. 1 is aside elevation of a typical and illustrative embodiment ofthe invention;

Fig. 2 is an end view of the device shown in Fig. 1 viewed from the leftof Fig. 1;

Fig. 3 is a cross-sectional view'taken along line 3-3 of Fig. 1, theouter shell being shown in partly removed position in the broken lines;

Fig. 4 is a cross-sectional view taken along line 4-4 of Fig. 1; and,

Fig. 5 is a fragmentary view of a modified embodiment of the invention.

The invention has for an objectrthe provision of an efficient device forthe separation of a mass of coins intermingled as to variousdenominations, the separation being effected by separating the coin ofdifferent diameter. The invention provides such a coin separator ofcompact and efi'icient design, simple to build and operate, which issmall enough to be easily transported so that it can be convenientlyused by the collector of coins from automatic dispensing machines andthe like.

Referring now in detail to the illustrative embodiments of the inventionshown by way of example in the accompanying drawings, and referringfirstto the embodiment of Figs. 1 to 4 inclusive, the coin separator is shownas comprising a perforated main drum cylindrical element In which ismounted forrotation upon a framework 'com'p'ris'ing inverted Y shapedframes II and 12' one at each end of the drum, the frames being held inspaced relationship to form a rigid framework by means of a plurality ofside rods l 3- extending between them.

As one end the main drum I0 is provided with a fixed circular head I4riveted thereto as shown, while the other end of the drum is closed by aremovable head IS. The inwardly turned flange portion l6 of head [5 isslotted at a plurality of spaced places as indicated by numeral [1 tofreceive screws l 8 which extend radially outwardly from and are securedin the main drum I0. Wing nuts IS on screws l8 may be tightened againstflange It to hold the circular head [5 in place on the drum, or may beloosened to allow.easy removal of the head axially of the drum. A handle20 is preferably provided on the head l5, and another handle 2| on thehead [4, to form grips for removing the drum from the framework, and theremovable head l5 from the drum. Y

The removable, rotatable mounting of main drum l0 on the frameworkincludes the open topped journal 25 on the Y frame 12 to receive thestub shaft 26 on the axis of the head and drum. The other Y frame II isprovided with an open topped journal part 21 nearer the drum l0 and aclosed journal part 28 adjacent thereto, wherein is r0 tatably securedthe shaft 29 of crank 30. The driving connection between the crank 30and the drum I0 is shown in detail in Fig. 4 of the drawings, comprisingthe driving head part 3| secured to crankshaft 29, having a rectangularextension 32 to be received within a relieved place 33 in the drivingpart 34 which is secured to'head I 4 by means of shaft 35. With theconstruction shown it will. be apparent that drum I 0 may be readilyremoved from its framework by simply lifting it upwardly, the shaft 26being raised out of journal 25, and the driving part 34 being raised outof journal part 21, the driving parts 3| and 34 being separated, withthe crank 30 left in its place on frame II.

The main drum I0 is provided with a plurality of apertures 37 thereinarranged preferably, as shown, in rows extending in spaced relationshipbetween the ends of the drum, with the apertures in adjacent rows beingstaggered with respect to each other. A removable outer shell 38 isprovided to fit closely around the drum and contact the outer surfacethereof, said shell having apertures 39 therein of slightly smallerdiameter than apertures 31, andarranged in the same relationship sothatwhen the shell is in place on the drum, each aperture 39 will bepositioned substantially coaxially with respect to its correspondingaperture 31 in the drum.

The 51161138 is somewhat shorter in overall secured to removable head I5the drum l0 and extend radially outwardly therefrom to be seated incorresponding apertures in the shell 38, the said pins serving aslocation devices in placing the shell on the drum so that the apertures31 and 39 will be found in the described relationship when the shell ismounted on the drum (as shown in Fig 3) 7 The internal surface of drum[0 is preferably provided with a liner 58 of rubber, cork, or similarmaterial for dampening and preventing the noise of the revolving mass ofcoins, and the end; 14' and i5 are likewise' provided with suchniaterial as indicatedby numeral 5i. The liner 5'Ei may be formed ofplurality of sections, as clearly shown in'Figg 3, with the adjacentends the omix and tumble the coins of the mass when rotated,

A pair of longitudinally extending plates or baffles 53 are providedbetween the frames H and l2, on e atleithers'ide of the drumrlfl,inorder to direct coins'fallin'g from the drum in its operation towardtl e tray 54, which is adapted to be removably positioned beneath thedrum and between' the legs of the endframes.

With the construction for a' coin separator hown an apparent. Afmixedmass. of coins such as', for instance, mightbecollected from anautomatic dispensing machine having coin changing means therein, wouldcomprise five, ten, and twenty-five cent pieces. The mass would beintroduced into e m w by r moving the. end' l5, the.end'

then replaced and tightened; and the drum Irioun'ted in' t heframeworkjwith the outer shell 38 in place about the drum. The drum .isthen' slowly rotatedffor severalrevolutions by crank 30,

and dimes. in the mass are dropped out into my idt foi gh apertures 31and39,.the' sizes of said apertures beingselected for purpose of theexample separation, so that dime'srand nickels w'il I tp'a'ss throughaperturesfl'l, dimes will pass through apertures 38 but not nickels, andquarters will pass through neither size, of aperture.

Aftei" ,the dimes have been dropped out, the

outer snares maybe easily einoved after loosen-,-

ing thelevered buckles 44','"the tray 54 removed and the dimes taken outor another tray put in plaoe, and further rotation ofthedrum drops'outthe nickelsinto the tray,'the quarters remaining alone within thedi um.I ,he quarterslare easily removable by taking the drum from theframewors ns removinghead l5, and the mixdmass of coins has thereby beenseparated into th'e various denominationspf different dlameters;

Fig; 5 of thedrawirigs discloses a mfodified embodiment of the inventionthe operationand construct i'on ofiwhich' are: entirely similar to thoseofthe embodiment j ust'disclussedgexcept that the anda removable head58, has an outer shell 59 of' one piece designadapted to beslipped overthe en'd'of the drum'when the head 58 isj'removed abutting and radiallyinwardly turned tov form ribs'52 extendinglongitudinally, of the drum.

described the 9P fation will be cieany 56 cooperates with slot 6! at theend of shell 59 to position the shell on the drum for properregistration of the apertures in each. In operation the drum and shellunit must be removed from the supporting frame and the head 58 removedin order to take off shell 59 during the course of separation.
